Tunable Fabry-Perot Filters

Open Photonics is working with VTT in Finland on the commercialization of their Piezo and MEMS tunable Fabry-Perot Filters.  VTT has studied MEMS- and Piezo-based FPIs since early 90’s. Their Fabry-Perot technology is an enabling platform towards smaller, lighter, smarter and cheaper sensors.

Fabry-Perot Interferometers can reduce the size of spectrometers significantly (to the size of matchbox) and price level can drop down to the level of tens euros/unit in large volumes.

We believe that the VTT FPI technology can revolutionize the micro spectrometer, spectral imaging and sensors markets dramatically.

Several demonstrators have been developed and are available for sale.  These demonstrators include MEMS and Piezo based hand held spectral cameras, near infrared and mid infrared spectrometers, and tunable light sources.
